Abstract Fuel injection properties, including the injection rate (temporal aspects) and spray behavior (spatial aspects), play a crucial role in the combustion efficiency and emissions of diesel engines. This study investigates the effects of different ethanol-biodiesel-diesel (EBD) blends on the injection performance in diesel engines. Experimental tests are conducted to examine key injection parameters, such as spray penetration distance, spray cone angle, and droplet size, alongside an analysis of coupling leakage. The main findings are as follows: (1) The injection behavior of ethanol and diesel differs significantly. The addition of ethanol reduces the density, viscosity, and… More >
